You'd be better served experiencing Five Nights at Freddy's 4 the way it was obviously intended to be enjoyed. By going on YouTube and watching some twenty-five-year-old, dressed like a fourteen-year-old, scream and cry his way through the game like a seven-year-old.
The game truly has come full circle.

The low price point means it's not a massive gamble to buy into Five Nights at Freddy's 4, but considering you've likely played the previous three games and have now spent around eight hours keeping homicidal animatronics at bay, there's nothing about this fourth game that begs for you to return. Instead spend the cash on a bag of snacks and some drinks, and watch someone else shriek loudly into a microphone for you.
